“…The Fe 2p spectra of PB is similar to PBN, shown in Figure 3f. Unlike PB (Figure 3h), the N 1s spectra of PBN in Figure 3g showed the presence of N=O (402.9 eV), which demonstrated the stable presence of nitro in PBN samples [39] . Furthermore, two peaks were identified at 397.8 and 339.6 eV, which were assigned to C=N and C−N‐, respectively [40] .…”

Prussian blue analogues (PBAs) are promising cathode materials for sodium‐ion batteries (SIBs) due to their tunable chemistry, open channel structure, and low cost. However, excessive crystal water and volume expansion can negatively impact the calendar lifetime of actual SIBs. In this study, a novel Iron nitroprusside (Fe[Fe(CN)5NO]) (PBN) was synthesized to effectively eliminate the detrimental effects of crystal water on the reversible capacity and cycling stability of PBA materials. Experiments and Density functional theory (DFT) calculations demonstrated that PBN has lower crystal water and volume expansion compared to Fe[Fe(CN)6] (PB). Also, N=O bond in PBN significantly reduces the diffusion potential of Na+ in the skeleton. Without any modification, the cathode material exhibited a capacity of up to 148.6 mAh g‐1 at 50 mA g‐1 while maintaining 102.9 mAh g‐1 after 200 cycles. This work expands our knowledge of the crystal structure of PBA cathode materials and facilitates the rational design of high‐quality PBA cathodes for SIBs.
